Just when things looked like they were hitting bottom- BlackBerry has a deal. Fairfax Financial- its biggest shareholder- will pay $4.7 billion dollars for the smartphone maker, taking it private. That works out to $9 a share for the Canadian company. Just last week BlackBerry warned it will report a quarterly loss of nearly a billion dollars. Sales will also be much worse than forecasts. BlackBerry is also laying off 4,500 workers- more than a third of its workforce.
